As 48 V electric passenger vehicles replace cars with 12 V electrical systems and internal combustion engines, Littelfuse innovates with solutions


Install BF Inline fuses along insulated wires that have cross-sections of between 10 mm2 and 35 mm2. Please know that these cable fuses only work when both of their terminals connect to wires carrying up to 32 volts. Also, these automotive inline fuses must be insulated by self-adhesive shrinking tubes. Littelfuse recommends using DERAY–IAKT 4:1, 24 mm tubes.
